IMPROVEMENT IN vSOLE-CHANNELINC- MACHINES.

Specification forming part 4of Letters Patent No. 141,025, dated July22, 1873 application led February 15, 1873.

To all whom it may concern:

Be it known that I, CYRUS C. BALLOU, of the city and county of Albanyand State of New York, have invented certain Improvements upon theGhanneling-Machineof Joseph B. Johnson, patented July 28, 1863, of whichpreviously channeled in the old and usual way.

The nature of my invention consists in combinin g, with the tubular andangular cutters of the machine, certain devices for automatically layingback and pressing down the flap of the channel at the same time that thechannel and groove are cut, thereby completing, at one operation, thechanneling and preparing the soles ready for the sewing-machine. It alsoconsists in constructing the plows as herein described.

As shown in the drawings, A is the head of the machine. B is a guide,attached to the 'head by means of screws b b, which pass throughyslotted holes in the guide, and allow of its adjustment. Projectingbackward from the lower part of the guide a guard, C, is con structed,in the form shown, which enters into the space formed in the angularknife and plow, and serves to give direction to the fold of the flap asit is passed backward from the knives. D is the angular knife, whichrequires to be adjusted at the proper distance below the foot of theguide B, for producing the required thickness of the flap. E is theplow, having a peculiarly-curved surface, as shown, by means of whichthe turning back of the lap is completed. 4It has a recess formed in itsface, into which is inserted the tubular knife'or groover F, for cuttingthe grooves for containing the stitches that secure the sole to vtheshoe. The groover upon its face is made to conform to the curved form ofthe face of the plow, and is retained in its position by the pin f. G Gare bolts for securing to the head A the knife D and plow E, in both ofwhich provision is made for their proper adjustment by means of theslotted holes g g. H is a roller, attached to the head of the machine bymeans of the bracket I. It stands directly behind the plow, and pressesdown the ap, after it has been turned back by the plow, in such athorough manner as to prevent its being caught bywthe needle of thesewing-machine while attaching the sole to the shoe. j

This roller also serves as an upper feed-roller, thereby enabling me todispense withthe roller usually placed upon the machine for that specialpurpose. The plow J, shown in Fig. 5, is made without a grooving-knife.Vlt is substituted in the lmachine for the knife I) and plow E, and isintended to be used upon soles that have been channeled and grooved inthe old and usual way, for turning back the flaps so as to pass underthe roller H. It is provided with the projecting point K, which entersthe groove for the purpose of removing the core left by the groover whenpreviously channeled, as above stated, and at the same time it guidesthe sole in its proper direction.

By constructing the plow E with a detachable groover, F, as hereinbeforedescribed, I am enabled to make them more perfectly than if madetogether; and it also has the further advantage of permitting thegroover to be renewed at pleasure when it becomes defective from use, orany Aother cause, without involving the expense of renewing the plow.

The work accomplished by my improvement has heretofore been performed byhand after the soles have been channeled by the cha-nneling-machine, andfor this work alone from four to ve operatives were required to open andlay back the work done by each channeling-machine. In this way the workwas very imperfectly done, the soles being frequently injured by beingindented by the hammer used for this purpose.

By the use of my improvement, it will be readil y seen that the samenumber of soles that eould only be channeled. and grooved by thenmeliine heretofore, can now be completed ready for the sewing-machinein 2t more pereci nimmer, in the saine time, and, by dispensing; withthe services of the extra operatives, at a reduced cost.

l do not broadly claim the use of the an gular and tubular knives l'orthe purpose of channeling the soles of shoes, as I am aware that theyhave heretofore been hnown mui useuior tnls purpose; but

What I cla-iin as my invention is- 1. The combination of the guide B,knife D, and groover F, with the plow E and roller H, when arranged tooperate as and for the purpose speeitied.

2. The plow E having a detachable groover, F, constructed substantiallyin the manner and for the purpose specified.

3. The plow J having zt projecting point, K, as and for the purposeherein set forth.
